摘要： The purpose of the invention is to fabricate a near field optical head capable of recording and reading high density information at high speed with excellent mass production. In the invention, stoppers having almost the same height as that of a tip of conical or pyramidal shape are disposed around the tip, a part of a pressing body covering the tip and the stoppers is displaced by an external force, a part of the pressing body having displaced is allowed to come into contact with an opaque film near the point of the tip and thereby an aperture is formed. According to a fabricating method of the invention, multiple apertures can be formed in a block. Thus, the near field optical head is excellent in mass production and the formed aperture has a structure of high optical efficiency and high resolution. Therefore, the near field optical head capable of performing recording/reading in high density and at high speed can be fabricated in excellent mass production.

摘要： The invention concerns a recording apparatus for reproducing information recorded on a recording medium by utilising near-field light. The recording apparatus comprises: an aperture element having a microscopic aperture to scatter near-field light; a light illuminating means for introducing illumination light to the recording medium such that near-field light is created on a surface of the recording medium, the illumination light comprising two different modulation frequencies; a first light detecting means for detecting first propagation light caused by the microscopic aperture scattering the near-field light having one of the two modulation frequencies, and for converting the detected first propagation light into a reproduced signal; a second light detecting means for detecting second propagation light caused by the microscopic aperture scattering the near-field light having the other of the two modulation frequencies, and for converting the detected second propagation light into a control signal; and a control means for controlling a spacing between the aperture element and the recording medium based on the control signal.
